Python - C interface : init not correctly done when using only C logger

[girardm]

With following code, no log displayed until logger.debug("ctrl: argv = %s", sys.argv) uncommented (or debug/quiet/verbose/full mode activated).

C code

#include <bxi/base/log.h>

// Create a logger for my module/main
SET_LOGGER(logger, "ctrl-c");

void log_stuff() {
  PANIC(logger, "Logger ctrl-c issue a panic(1) message");
  ALERT(logger, "Logger ctrl-c issue a alert(2) message");
  CRITICAL(logger, "Logger ctrl-c issue a critical(3) message");
  ERROR(logger, "Logger ctrl-c issue a error(4) message");
  WARNING(logger, "Logger ctrl-c issue a warning(5) message");
  NOTICE(logger, "Logger ctrl-c issue a notice(6) message");
  OUT(logger, "Logger ctrl-c issue a normal(7) message");
  INFO(logger, "Logger ctrl-c issue a info(8) message");
  DEBUG(logger, "Logger ctrl-c issue a debug(9) message");
  FINE(logger, "Logger ctrl-c issue a fine(10) message");
  TRACE(logger, "Logger ctrl-c issue a trace(11) message");
  LOWEST(logger, "Logger ctrl-c issue a lowest(12) message");
}

Python code

logger = logging.getLogger('ctrl')

    log_config = { 'handlers': [ 'console' ],
                   'console': {
